Abstract (en)
[origin: EP3699126A1] Provided are a sheet supply device and a sheet supply method capable of accurately joining a sheet of a first roll to a sheet of a second roll. A controller (5) includes a shaft control unit (5e) that controls driving of a shaft drive source (4k) such that a standby side roll is rotated, and a unit control unit (5g) that presses a pressing roller (4e) against an outer peripheral surface of the standby side roll via a sheet of a supply side roll by performing torque control on a unit drive source (4c3) in a state in which the pressing roller (4e) is positioned in an area from a control switching position (P3) to the outer peripheral surface of the standby side roll together with performing position control on the unit drive source (4c3) in a state in which the pressing roller (4e) is positioned in an area farther away from the standby side roll than the control switching position (P3) away from the outer peripheral surface of the standby side roll by a preset distance while the standby side roll is rotated by the shaft control unit (5e).
